Coal hydropyrolysis permits product yield variation. [Riser cracking]

Conference ·
OSTI ID:7017215
Short residence time pyrolysis of coal in the presence of hydrogen at moderate pressure (hydropyrolysis) generates an interesting slate of chemicals, intermediates, and petrochemical feedstocks. IGT has been hydropyrolyzing North Dakota lignite in a DOE-sponsored project designed to maximize gasoline constituents called ''Riser Cracking of Coal.'' The product yield spectrum in this work includes methane, ethane, BTX, phenol, naphthalene, and cresols. The effect of operating conditions on the distribution of products is discussed. Process flexibility is explored by way of some preliminary economics, and potential commercial applications are examined.
